Hayek, who is married to Francois-Henri Pinault, the CEO of luxury group Kering, rocked her pink waves like she was born with them, but the look was fleeting. By the next day, she was back to her trademark dark tresses, though she still paid homage to pink with her retro jumpsuit and bag.

Hayek's dramatic color change was an especially big deal because we're so used to seeing the actress sporting dark strands.

She looked picture perfect with her classic brunette waves at the Oscars in 2003. (Also, can we talk about how she appears to not have aged a day since then?)
